GUSTAVUS I4. STUEBNIER, OF FLUSHING, NEW YORK.

DUMPING-BUCKET.

To all whom it may concern:

Be it known that I, GUsTAvUs L. STUEB- man, a citizen of the United States, and a resident of Flushing, in the county of Queens and State of New York, have invented certain new and useful Improvements in a Dumping-Bucket, of which the following is a specification.

This invention relates to a dumping bucket, and its organization comprises locking and dumping means that coact with each other and prevent the tilting of the bucket before being dumped, in case it should meet with an obstruction. Means are provided to enable the body of the bucket to be locked in an upright position and in position when dumping.

Figure 1 represents a side view of theimproved bucket, Fig. 2 shows a right hand side view of Fig. 1, F1g. 3 1s a top v ew of Fig. 1, Fig. 4 represents a side view of the bucket with its movable elements located in a changed position, Fig. 5 shows a slde View of the bucket positioned to dump its charge,

Fig. 6 represents a side View of a modification of the bucket, Fig. 7 is a right hand sideview of Fig. 6, Fig. 8 shows a top plan- View of Fig. 6 and Fig. 9 shows a side view of the modified bucket 1n posltion to dump Referring to Figs. 1 to 5, thebody of the bucket is shown at with the nose20 and with an eye 26 and locking hook 27 is pivoted on the pins 23. A pair of lugs 28 with openings for a pivot 30 extends from the eye 26. A latch 33 with the hook 34 and curved clamping flange 35 is pivoted on the pivot 30. The curvature of the outer surface 36 of the flange 35 is struck with an are having its center coincident with the axis of the pivot 30. A pair of locking pins 40 extend from the sides of the body 20 of the bucket which lock with hooks 27 when the bail is in a vertical position. A pair of guide pins 41 extend from the sides of the body 20 of the bucket and which bear against the outer surfaces of the hooks 27 when the latter are lowered.

To the rear wall of the bucket is secured a bearing block 42 with a curved bearing surface 44 of a curvature similar to the surface Specification of Letters Patent.

36 of the flange 35, and which locks with the said clamping flange 35, when the bail 25 is in its lowered position. v A bearing bar 43 is fastened to the rear wall of the body 20, to support thebail 25 when the latter is in its lowered position.

To use the bucket it may be supposed to have its elements positioned as represented in Figs. 1 to 3 and that it has been charged with its load. I The operator raises the bucket by means of a chain, rope or other suitable means not shown connected to the eye 26, and the locking hooks 27 looking with the locking pins 40, prevent the bucket from tilting or being dumped, in case it comes in contact with any interference during its movement from one position to another. lVhen the operator is ready to dump the bucket, it is lowered to a platform or the ground, and the chain or rope connected to the eye 26 is payed out to lower the bail 25, so that the locking hooks 27 become disengaged from the locking pins 40. During the descent of the hooks 27 their outer surfaces bear against the guide pins 41 and the bail automatically swings down to the position shown in Fig. 4 supported on the bearing bar 43 and the latch 33 takes the position shown in said Fig. 4. The clamping flange 35 is now opposite the clamping block 42 and ready to bear against the same. The operator next raises the eye 26 and the bucket is turned and dumps its load, taking the position shown in Fig. 5. The bucket is now brought back to the place where it is to be charged and lowered. The nose 2O strikes the ground or charging platform and upon paying out the rope connected to the eye 26, the bucket assumes the position shown in Fig. 4. The bucket is now charged and then the operator releases the latch 33, which permits the bail to take its normal Vertical position as shown in Fig. 1.

Referring to Figs. 6 to 9 which shows a modification of the invention, the body of the bucket is indicated at with the nose 50, and from the sides of the bucket extend the bail pins 51 that support the bail 52 having the eye 53. From the sides of the body 50 of the bucket extend the supporting pins 54, for the bail 52 when the latter is in its lowered position. Stops 55 extend from the sides of the body of the bucket for the bail to bear against when the said body is in an upright position. The bail 52 carries a latch 58 similar to 33, and to the rear wall of the body 50 is fastened a bearing block 59 similar to 4:2.

To use the modified form of bucket it may be supposed to have its elements positioned as shown in full lines in Figs. 6, 7 and 8, the bucket being in its upright position and charged with its load. To dump the bucket it is placed on a support and a chain connected with the eye 53 is payed out thereby lowering and swinging down the bail 52 to the position shown in dotted lines in Fig. 6, the said bail bearing on the pins 5- 1. In this position of the bail 52, the latch 58 is ready to engage the bearing block 59. The operator next pulls on the rope or chain connected with the eye 53 and the bucket is turned to the position shown in Fig. 9 when the contents thereof are dis charged. To turn the bucket to its normally upright position, the nose 50 is brought to touch the ground and the bucket is allowed to swing to the position shown in Fig. 6, the bail being locked to the body of the bucket as indicated in dotted lines. The latch 58 is then unlocked from the bail by raising its swinging end after which the bucket may be swung to its normally upright position.

Having described my invention what I desire to secure by Letters Patent and claim is:

1. In a bucket of the character described the combination of a body therefor, locking pins extending from the side of said body, a

swinging bail slidably connected to the body of the bucket, locking means on the bail to lock with said locking pins when the bucket is in its normally upright position, a bearing block extending from the body of the bucket locking means carried on the bail to automatically lock with said bearing block when the bail is in its lowered position.

2. In a bucket of the character described the combination of a body therefor, a swinging bail for said body, a latch pivoted to the bail and having a hook at one end to lock with said bail and having a curved bearing surface at the other end, a bearing block carried on the body of the bucket with a curved bearing surface to engage the end of the saidlatch having the curved bearing surface.

3. In a bucket of the character described the combination of a body, a pair-of clevises on the sides of the bucket, a slidable bar Copies of this patent may be obtained for five cents each, by addressing the. Commissioner, of Iatenta,

guided in each clevis, a bail with a looking hook on each of its legs pivoted to said bar and locking pins extending from the side of said body to lock with said hooks.

at. In a bucket the combination of a bail, a latch with a hook at one end and a curved bearing flange at the other end pivoted to the bail, guide pins on the side of the body of the bucket to engage the bail when being lowered and a bearing block extending from the rear wall of the body of the bucket to engage the curved bearing flange of the said latch when the bail is positioned to enable the bucket to dump its charge.

5. In a bucket of the character described the combination of a body therefor, a slidable bar guided on each of a pair of opposite sides of the body of the bucket, a bail with its ends pivoted to said bars and having a locking hook formed therewith and means on said body to lock with said hook.

6. In a bucket of the character described the combination of a body therefor, a pivoted bail for said body, a latch pivoted to and normally locked with said bail when the body is in its upright position and a bearing block on the body of the bucket to lock with the said latch when the bail is inclined to its normal position.

7. In a bucket the combination of a body, a locking pin extending from a side of said body, a swinging bail slidablyconnected to the body of the bucket, locking means on the bail to lock with said locking pin when the bucket is in its normally upright position and locking means carried on the bail to antomatically lock said bucket in position when said bail is in its lowered position.

8. In a bucket the combination of a body, a swinging bail slidably connected to body of the bucket, means to lock said bail with said body when the bucket is in its normally upright position, a bearing block extending from the body of the bucket and locking means carried on the bail to automatically lock with said bearing block when the bail is in its lowered position.
